Walter,
Thanks for posting your findings. We're holding out still here w/ FCP 7 until Autodesk Smoke 2013 pre-release is available for testing, at which time we'll be pitting FC10 against Premier Pro CS6 and Smoke.

I'm curious what sorts of issues you experienced with the Kona LHe and Premier Pro CS6? If you recall would you mind mentioning which AJA driver version were you using when you had these issues? If you were having audio/video dropouts was your monitoring equipment connected to the AJA's HDMI port or SDI? How were you taking audio out of the kona? embedded? XLR?
